Segment drawn on scale having end points O (0,0) and A is a line segment.
O A=
O A =
=
=
Now , the same segment actual structure having end points O'(0,0) and B (30,36) is also a line segment.
O'B=
=
=
= 2√549
[Cancelling √549 from numerator and denominator]
So, Actual length = 40 × Length on scale
When we round a number the new rounded <span>number is </span>simpler but the value is kept close to what it was. The common method for rounding numbers is the following: we d<span><span>ecide which is the last digit to keep and l</span><span>eave this digit the same the same if the next digit is less than 5 or increase it by 1 if the next digit is bigger than 5.
</span></span>Because the next digit matter, it is not possible for a 5 digit number to be rounded to 6 digit number.
